Place potatoes in a medium saucepan, cover with cold water, heat to boiling, reduce the heat and simmer until cooked through, about 12 to 16 minutes. Drain in a colander. Immediately place potatoes back in pot you cooked them in and place on same burner, which has been turned off. Stir occasionally over next 5 minutes to let potatoes dry out.
In a small saucepan, warm buttermilk over medium low heat. Do not boil. Pass potatoes through a ricer or food mill. Alternatively, leave potatoes in pot and mash by hand using a potato masher or wooden spoon. Stir in enough warmed buttermilk to obtain desired consistency. Add salt and cracked black pepper to taste, stir until combined. Add sambal oelek, a teaspoon at a time, tasting after each addition. Serve immediately.
MORPH: The morph on this is a simple dish called baked egg mashed potatoes. All you do is place leftover mashed potatoes in a shallow baking dish. Make wells, crack eggs into the wells, cover with a thin layer of cheese and bake until the eggs are set.
